Winters are relatively mild and often snow-free, springs are short and with sudden shifts from cold to warm seasons, and summers are quite hot and sometimes with heavy rainfall.

Autumn is generally marked by good weather, although sometimes, towards the end of this season, there are frosts and snows damaging the crops.

The plants found in this area are part of different categories of floristic elements, predominating the Central European one with strong Mediterranean influences.

Corylus avellana (hazel), Sambucus nigra (black elderberry), Rosa canina (dog rose), Prunus spinosa (blackthorn), Salix purpurea (purple willow), Humulus lupulus (hop), Syringa vulgaris (lilac), Berberis vulgaris (barberry) and numerous other shrub and semi-shrub species grow here.

[4] The intensive development of agriculture, the cutting of the oak forest near Lenauheim, and more recently of the edges of black locust and the clumps of weeping willows and poplars led to the limitation of the animal species that populate this region.

During milder winters there are some species of birds that are not commonly found in the area and in its surroundings: little and great bittern, glossy ibis, northern lapwing, water rail, green and black woodpecker, etc.

[6] Mammals found here include deer, fox, hare, hamster, suslik, field mouse, some of which are harmful to agricultural crops.

Between 1311 and 1415 are recorded the presence of several landlords, including Mathias von Csatád from which comes the old name of the village – Cetad.

Historian Ágoston Bárány suggests that the name derives from the Romanian word cetate ("citadel"), invoking the existence around 1845 of some old foundations identified within the commune's borders.

By that time, Cetad was ravaged by Ottoman incursions; a document of 23 March 1482 mentions it as a puszta (Hungarian for "deserted").

It is assumed that these underground tunnels built of brick with hot lime mortar were specific to some reinforcements from the Banat Plain and were ways of retreat in case of danger.

In 1925, with the Law for Administrative Unification, the name of the commune changed from Cetad to Lenauheim, after the German-language poet Nikolaus Lenau, born here in 1802.

The first German (Swabian) colonists began to settle in Bulgăruș in early 1769 and came from Lotharingia, Luxembourg, Upper Austria and Hesse.

Each received a plot for house, 34 jugers of land, construction materials and was granted various privileges and tax exemptions.

Heavy fighting took place on 8 August 1849 between Bulgăruș and Cetad (present-day Lenauheim), resulting in numerous deaths and injuries among the villagers.

The name Grabaț is of Slavic origin and already existed when the first Swabians arrived here, but it did not describe a specific settlement, but rather an area sporadically inhabited by Serbian cattle breeders.

Count Mercy's map of 1723 shows a praedium (estate) called Grabatz, although the village did not exist at that time.

Within this colonization program, the imperial administration of Banat ordered the creation in the Grabatz estate of a new settlement for German (Swabian) colonists.

Johann Wilhelm Edler von Hildebrand [de], the administrative adviser to the Imperial Court in Vienna, was responsible for the establishment of the colony.
